摘要
基于电液伺服控制原理,将工程车辆2个驱动轮的输出转速分别作为伺服系统的激励和响应,设计了一种新型的工程车辆液压传动系统。通过人为调整反馈通道比例系数K,实现车辆的直行和转向控制。针对本系统,应用仿真软件AMESim进行了相应的仿真分析。结果表明:该系统能够有效地完成直行和转向动作,整个过程响应迅速、运行平稳、控制精度较高。
Based on the principle of electro-hydraulic servo control and that the output speeds of two driving wheels of engineering vehicle are taken as the excitation and response for servo system respectively, a new type of hydraulic transmission system for engineering vehicle is designed. The straight and turning control for engineering vehicle is realized by adjusting the proportion coefficient K in the feedback channel artificially. For this system, the corre- sponding simulation analysis is done with the simulation software AMESim. The results show that the system can complete the straight and turning movements effectively.
